These are specifically sized medium, extra short, 10-12
I am chaparra 😉
Check out the awesome specifications, and the tape measure getting a good measure of the bend overreach as well as the side to side, hip to hip and the pocket sizes

SPE1C 1–14 – D – 1048
These are the real deal purchased on military base and just never really used, machine wash in cold water
These are the real ones so they are fireproof and fiber content, 50% nylon, 50% cotton rip top
Again, these are G.I. , Purchased right at an army as well as Air Force Base joint base
Like I say, I will list them as used, but you can see the neat way that the actual camo is and the “wear “look 
But everything about them is just awesome and guaranteed you will love it
